Inthe field of science, the topic of climate change has persisted, andit is defined as the lasting significant shifts in weather conditionswhich are measured by continuous variations of climatic parameterssuch as temperature, rainfall and wind (Lavellet al., 2012).Climate change can also refer to the increase in the mean temperatureover the Earth surface. The climatic variations may be due to thenatural processes or through the human actions or both. Thisinternational climate alteration has previously resulted in certainchanges on the environment. The paper insights into the globalclimate changing processes due to primarily human activities, effectsthe shifts impose on the biosphere and in human life, reduction ofgreenhouse emissions and their major impacts (by percentage) to theenvironment. Similarly, the study explores the changes intechnologies that can help reduce greenhouse gasses’ effectsalongside the hindrances encountered while exploiting thesetechnologies.
Overan extended period of time, human activities have led to a highrelease of carbon dioxide and other greenhouse gasses into theatmosphere leading to the greenhouse effect. According to Gallina(2016),projections have been made of an increase in temperature globally dueto human actions causing man-made climate modification which willcontinue to change in years to come. Climate change will contributeto both average and life-threatening weather conditions to the humanpopulation, and that would be the manifest in severe droughts besidesheat waves, torrential downpour causing overflows, and or severestorms.
Theconsequences are dangerous to the humanity in the eventuality ofoccurrence, hence a serious area of concern in the discipline ofclimatology. For instance, man-made climate leads to rising sealevels that affect the coastal areas where the majority ofcommunities are always concentrated properties are often damaged andresidents evacuated under such conditions(Harding et al., 2015).Moreover, climate change always has adverse impacts on the watersupplies, agriculture, power generation, transport system, andnatural environment as a whole. In climate modification, there arealways opportunities other than risks although effects are alwaysbecoming progressively negative as the global surface temperaturesbecome gradually warmer.
CriticalPositive Feedback Effects Causing Rapid Acceleration Change
Understandingthe positive feedback impacts of worldwide man-made climate variationis very vital as it helps to determine the sensitivity of climatechanges and the future climatic state as well as how to avert thenegative response of the climate transformation. Kurz(2015) argued thatin the modification of climate, positive feedback will always lead toaccelerating response, which would either make the climate warmer orcolder. The greatest vital and recognizable positive reaction is thewater vapour which although, is a greenhouse gas with negligibleeffect on the external factor controlling the type of weather.Heating of the global atmosphere leads to an increase in water vapourin the atmosphere hence the gradual increase of the greenhouse effectreducing the expanse of heat escaping out of the Earth. Therefore,there will be an increase in atmospheric warming enabling more watervapour to be held in the atmosphere, thus the rapid accelerationchange (Kurz et al., 2015). Moreover, another critical feedbackaccelerating the change is the greenhouse gas known as Methane whichis always trapped in frozen peat bogs as well as the water ice belowthe sea floor sediment. Increase in atmospheric temperature leads todefrosting of the peat bogs releasing the methane gas causing intensewarming the earth atmosphere. Other critical feedbacks include forestdieback, clouds, and ice—albedo all crucial in accelerating thechange. Climate change is gradual it consequently, have theprogressions involved.
Processof and Significant Results on the Biosphere and onHuman Life
Atmosphericweather changes from day to day because of the observed shifts in theclimatic system such as clouds and precipitation. The global climatehas been under variation many times based on the planets history,starting with ice ages to long periods of significant warmth which issignificantly caused by emissions of greenhouse gasses(Lavell et al, 2012).This interference leads to increased air and ocean temperatures.Climate change affects human way of life in so many ways theexposition to high temperatures frequency and heat waves always posea threat. There are always increasing prevalence of certain diseasesdue worsening of air and water quality. Besides, severe weatherevents caused by climate change can lead to losses of property andthat causes costly disruptions to the society and with a reducedavailability and affordability of insurance, this might change anindividual social way of life. To the biosphere, climatic adjustmenteffects have led to decrease in surface reflectivity at high latitudecausing intensification in solar radiation absorption temperature isthus transferred (and concentrated) to the atmosphere as a result ofgreenhouse gas emission (Lavellet al, 2012).
Contributorsof Greenhouse Gases
Thecurrent climate fluctuations based on the emission of greenhousegases cannot be enlightened through natural roots for instancevolcanic explosions. According to Paustian(2016),the key contributors of the greenhouse gas productions over theprevious half a century are the human doings. Some of theseactivities include combustion of fossil fuels, fuels from heat andenergy, clearing of vegetation plantations, fertilizing crops,storage of leftover in landfills, and the raising livestock besidesproduction of particular type of industrial manufactured goods.Others human activities are, constructions, vehicles transporting andautomobiles, use of oil and natural gas, chemical industry and metalproduction. All these generate greenhouse gases and compound theeffect that enhance global heating(Babcock et al., 2016).Thus, there is a stressed need to work towards reducing the releaseof these gases into the earth atmosphere to escape fatal outcomes ofclimate modification.
Waysto Reduce Greenhouse Gases Emissions
Someof the mitigation measures that have been taken to reduce Greenhousegases emissions have an absolute cost. However, they contribute toeconomic benefit by reducing the adverse impacts of climate change.The first way of combating the release of greenhouse gases is byencouraging people to purchase products with minimal packaging aimedto reduce waste products. Second, by using smaller amount heatalongside air conditioning by putting more connections/installationsto the walls and fitting weather stripping everywhere especiallyaround the doors and windows is also helpful (McCarlet al., 2016)..Also, individuals are encouraged to drive less and smart as it willreduce emissions of gases. Finally, involving other means oftransport like walking and biking and the planting more trees is alsoadvisable, with the latter playing a role in absorbing the carbondioxide which is a greenhouse gas and giving out oxygen.
Changesin Technologies are Realistically Reducing Effects
Newtechnologies have been adopted as a way of mitigations to minimizethe Greenhouse gases productions and manage their effects. Changes intechnology realized are the Power-Tower solar and photovoltaic solarpanels on every roof which supply electricity lighting bulbs, unlikethe electricity that is generated by turbine turning. Also, upgradingof infrastructures for instance highways plus transmission linesdecreases greenhouse gases emissions as vehicles are driveneconomically(Lehmann et al., 2015)..Similarly, excellent driving skills and vehicle maintenance have beenimplemented, and it is paramount as tires will remain inflated tolimit the amount of greenhouse gases emitted from vehicles. Furthermore, agricultural practices have been improved tremendouslye.g., the increase in crop resilience, paper cycling, and forestmanagement, harmonizing the amount of wood taken out compared to anumber of trees that are planted. Therefore, this mass discharge ofthe unfriendly environmental gases will significantly lessen.Biodiesel electrical vehicles which offer the finest transportresolution with no emissions of harmful gases alongside othertechnologies such as the protection of coastline resources by use ofstructural walls and overflow accommodation through elevation haveproved efficient in controlling climate change impacts (Shackletonet al., 2015).However, regardless of innovative technologies introduced to act as amitigation of climate modification by decreasing the productions ofthe greenhouse gases, they are welcomed with several challenges.
Hindranceto the Implementation of Technology
Whenwe turn to new designing, developing and implementing thetechnologies that have wider effects on individual effects ofgreenhouse gases face new sets of challenges. Based on Shackleton(2015) argument, the major challenge relates to the use of renewableenergy sources their supply are always very intermittent and theelectricity generated cannot be stored enough for future use. Specific technologies, when implemented, will automatically lead tojob loss of some individuals. Moreover, some of the technologiesrequire large capital and thus unlikely to be afforded in thedeveloping countries. Consequently, some nations are unwilling toadopt the change required for further implementation of thesemachineries(Long et al., (2016).Similarly, some technologies are specific to particular gas controland thus allow the release of other gases, hence the adaptive toreduce the most climate change vulnerabilities is constraining.
Keepingthe Global Average Temperature below 2 Degrees Celsius
Thelevel of climate change will greatly rely on how quickly and greatlywe can minimize the release of the greenhouse gases by making choicesto reduce the the climate change negative impacts and risks.According to thereport by Intergovernmental Panel on (IPCC) (2015),global temperatures will continue to increase for decades to come by0.5oFto 8.60Fby 2016, with a possibility increase of at least 2.0oFsimply because of the greenhouse gases produced by human activities(Long et al., 2016).Regardless of the attempt to reduce the greenhouse gases emissions,temperature will possibly rise since some variations to the climaticconditions are beyond controllable. Carbon dioxide can be inexistence in the atmosphere for almost a century for it to getdepleted, other gases also naturally occur. This increase intemperature will be critical because any slight intensification inEarth’s temperature have severe impacts (Longet al., 2016).Therefore, actions are required to be put into practice for thesafety of our natural environment, health and safekeeping as thepossibility of keeping the temperature rise rates below 2oCis almost impractical.
Humanactions as a crucial cause of climate modification is alreadyaffecting societies and environments all over the world, andprojections showcase severe increase it impacts. The greaterpercentage of gases present in the atmosphere are not naturallyinduced but through human-induced activities. It is, therefore, verycritical for each and every individual to make choices for a bettertomorrow depending on the type of activities they are practicing.That way, it would be possible to ensure the reduction of severeweather phenomena occurrence as caused by climate change.
